Disney/Marvel screencap
Samuel L. Jackson, playing spy Nick Fury, was pleased to be involved in the writing process but had one request, as Whedon recalls in "Joss Whedon: The Biography," out August 1:
"I don't want to run," the then-62-year-old actor said. "Don't make me run a lot."
After reading the script, however, he confronted the director over a stage direction.
"It says, 'Fury run," Jackson said.
"I know, it's just this one time," Whedon said.

This isn't the first time Jackson has had a request on set of a major motion picture.
While filming "Star Wars: Episode II - The Clone Wars," Jackson requested a purple lightsaber for his character Jedi Master Mace Windu so he could find himself in a big action-sequence of around 300 lightsabers.
Jackson recounted that George Lucas originally tried to tell him lightsabers only came in three colors but eventually relented.
